Example: ``` session.users.create('myuser','rodsuser',user_zone='otherzone') session.users.create('myuser','rodsuser',) ``` The second command raises `MultipleResultsFound` when running` [UserManager].get( user, zone )` at the end of the` create( )` call. Solution most likely: in userManager.get, force user_zone to expand to the full local zone name when given as an empty param ("") This bug occurs also when a groupadmin is calling `create_with_password`
